Benefits of technology

[0017] When the end effector makes use of fluid pressure, fluid supply piping is caused to pass through the inside of the hollow rotary shaft likewise the case of the electric wiring or airtightly connected to the mounting portion opposite to the mounting portion of the end effector. With this arrangement, an advantage similar to that of the electric wiring can be obtained.
[0018] Further, according to the present invention, the mounting portion of the end effector may be

Embodiment 1

[0038]FIG. 1 is a side elevational view of a horizontal articulated robot of an embodiment 1 according to the present invention, FIG. 2 is an upper surface view of the horizontal articulated robot, and FIG. 3 is a perspective view of the horizontal articulated robot. Further, FIG. 4 is a sectional view showing an arm portion of the horizontal articulated robot.

[0039] The horizontal articulated robot 10 includes a base 11, an arm base 13 coupled with the base 11 through an up / down movement mechanism 12, a first arm 15 coupled with the arm base 13 through a first joint shaft 14, a second arm 17 coupled with the first arm 15 through a second joint shaft 16, and a working shaft 18 rotatably disposed to the extreme end of the second arm 17.

[0040] The first and second arms 15 and 17 are horizontal arms that turn in a horizontal surface, and the second arm 17 constitutes an extreme end arm. Further, the number of the arms is not particularly limited and ordinarily set betwee...

Example

Embodiment 2

[0056]FIG. 8 is a sectional view of the portion of a second arm 17 in a horizontal articulated robot of an embodiment 2 according to the present invention.

[0057] Although the embodiment 1 described above shows the hollow mounting flanges 18b, 18c disposed to both the upper and lower ends of the hollow rotary shaft 18a, the embodiment 2 shows a hollow rotary shaft 18e having a hollow mounting flange disposed on one side, for example, an upper hollow mounting flange 18b. Further, the lower portion of the hollow rotary shaft 18e extends somewhat long toward the lower side of the second arm 17. A required assembly job can be executed by mounting a not shown tool (for example, screwdriver, welding torch, and the like) on the projecting portion extending downward.

Example

Embodiment 3

[0058]FIG. 9 is a configurational view of a coupling means which couples a hollow rotary shaft 18a with an end effector 25 and shows an embodiment 3 according to the present invention, wherein (A) is a sectional view of a coupling state, (B) is a lower surface view on a hollow rotary shaft side, and (C) is an upper surface view on a coupling means side.

[0059] Although the hollow rotary shaft 18a is coupled with the end effector by the flange coupling in the embodiments 1 and 2 described above, the embodiment 3 is arranged such that they can be coupled with each other by screw coupling in an instant mounting / dismounting system.

[0060] More specifically, a coupling 33, which has a female screw 32 cut thereto, is disposed to a hollow cylinder 31 having an end effector 25 previously mounted on the lower end thereof. Further, the hollow cylinder 31 has a positioning key 34 disposed thereto. A coupling means on the end effector 25 side is arranged by the arrangement describe...

Abstract

A horizontal articulated robot has a plurality of horizontal arms coupled by joint shafts, and a working shaft disposed at the extreme end of an extreme end arm among the horizontal arms has mounting portions of an end effector formed to both the upper and lower ends thereof. With this arrangement, there can be provided a horizontal articulated robot that can cope with various work transport forms and various types of works by one type of a robot by selectively using the upper and lower sides of a working shaft.

Description

[0001] The entire disclosure of Japanese Patent Application No. 2004-363919, filed Dec. 16, 2004, is expressly incorporated by reference herein. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to an horizontal articulated robot, and more particularly, to a structure of mounting portions of an end effector mounted at the extreme end of a robot arm. [0004] 2. Description of the Related Art [0005] Horizontal articulated robots, which are also called scalar robots, are excellent particularly in compactness and workability and often used in industrial robots. The horizontal articulated robot has such a structure that ordinarily, first and second arms turn each in a respective horizontal plane through first and second joint shafts, respectively and an end effector such as a hand and the like is mounted on a working shaft attached to the extreme end of the second arm to thereby cause the end effector to execute a desired job such as an asse...
